Any feedback is welcome. Thanks!

Sure I haven't come across anything that someone else hasn't already pointed
out, but here it is any:
P133 "Table 9.1 on page 301 summarizes dynamic array operations"
should read
"Table 3.4 on page 134 summarizes dynamic array operations"
Thanks, I'd forgotten to clean the intermediate files before building
the entire book.
P118 something sounds wrong here also:
"However, if a function returns T[n], that not automatically
converted to T[]--it must be T[n]."
maybe "it is not automatically" vice "that not automatically"?
P117 this sentence does not sound natural to me;
"This means that copying arrays, passing arrays into functions,
and returning arrays from functions -- these all
copy entire arrays."
P111 change "in it" on line 8 to read "into it"
P111 change "bailout" on line 21 to read "bail out"
P110 change "responsible in making" to "responsible for making"
Not clear what you are saying here:
"The compiler is free to assume that when optimizing the operations into
primitive vector operations offered by the host processor."
What is it assuming? That I'm responsible? That the arrays do not overlap?
P109
auto a = [1.0, 2.5, 3.6];
auto b = [4.5, 5.5, 1.4];
auto c = new double[3]; // changing to "auto c = (new double[3])[] = 0.0;" or adding
the line "c[] = 0.0;" should do the trick
c[] += 4 * a[] + b[];
will not work. Since c is of type double[3] it's initial value is set to
[nan, nan, nan];
As a result any transaction performed on this array will result in the
same if it is not first initialized.
P102 eenlists should read enlists
P101 change "comes just handy" to "comes in handy"
Thanks! Quite a few of these are new. I've added this to my worklist,
and as I see you give no email and no name, please email me privately
your name so I can add it to acknowledgments. (I'll do so for everyone
who sent me feedback.)
